11kv 15kv 33kv Wholesale Zinc Oxide Lightning Arrester

The lightning arrester is an appliance used to protect electrical equipment from high transient overvoltages and to limit the duration and often the magnitude of the renewed current.Note 1: Surge arresters are usually connected between the grid conductor and ground, however, they are sometimes connected next to the appliance windings or between the conductors.Note 2: Lightning arrester is sometimes called overvoltage protector, overvoltage limiter (surge divider).Lightning arresters are another important piece of equipment often used to protect communication cables from lightning damage.Scope of applicationAC gapless metal oxide surge arresters are used to protect the insulation of AC power transmission and transformation equipment from lightning overvoltage and operational overvoltage damage. They are suitable for overvoltage protection of transformers, transmission lines, distribution panels, switchgear, power metering boxes, vacuum switches, shunt compensation capacitors, rotating motors and semiconductor devices.ClassificationSurge arrester is divided into many kinds, there are metal oxide surge arrester, line-type metal oxide surge arrester, gapless line-type metal oxide surge arrester, full-insulation composite jacket metal oxide surge arrester, removable surge arrester.The main types of surge arresters are tube-type surge arresters, valve-type surge arresters and zinc oxide surge arresters. The main working principle of each type of lightning arrester is different, but the essence of their work is the same, are designed to protect communication cables and communication equipment from damage.  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
